2 Claims.

The purpose of this invention. is to provide. improvements in the designof a mop of the type used for floors or other surfaces, and in which ablock of sponge rubber or other similar material may be used; in whichboth edges of the mop are available for use, and also in whichthe. mopmay beheld in; one hand while. it: is turned. over from, one side to theother and, wrung. by thev other.

Devices of this nature have. been. provided wherein the mop is attachedto. the handle and may be wrung independently or. by forcing platesagainst the. sides, however, these devices are in.- convenient, and,therefore, it is desirable to improve the construction, andprovidesuch amop in which the ,mop may be permanently held by. a handle from oneside, and a member pressed against thehandle by the thumb or by theother hand when it is desired. to wring, the mop, and also in which themop may. be turned. over so that either edge is, available for use.

The object of this invention is, therefore, to provide improvementsinthe construction of mops,. wherein a; handle is attached to one sideand a holding plate to theother, in which the plate may be forced.against thehandle from either the top or, bottom to wring the mop.

AHOthGIgbil-ECT; is to; provide improvements in a mop of this type, inwhich either surface of. the.

mop may be used.

Another object is. to provide improvements in,

mops of this type, in which the mop is readily.

detached from the handle.

Another object is to provide improvements in mops of this type, inwhichthe mop ishinged about the end of a handle and held inworkingposition by a holding means adapted to beapplied from. either side.

A further object is to'provide a mop of this type in which plates arenormally permanently secured. to the opposite sides of the mop, andthese plates are providedwith removable holding. means for the handleand a. wringing plate.

And a. still further object. is toprovide a mop I :of this type, inwhich bothedges are available for use, and in which both sides may bewrung by pressing them against the handle which is of a simple andeconomical construction.

With these ends in view the invention embodies a mop comprising a blockof sponge rubber or other suitable material, plates permanently attachedto the opposite sides of said block with hinge members extending outwardtherefrom, a plate held in the said hinge members at one side of theblock having handle holding means permanently mounted thereon, anothersimilar plate hingedly attached to the opposite side of the block andpositioned to extend backward from either'side of the block, and meansremovably holding said latter plate to the plate upon which the handleis mounted.

Other features and advantages of the invention will appear from thefollowing description taken in connection with the drawing, wherein:

Figure 1 shows a general view of the mop.

Figure 2 is a plan view of the mop.

Figure 3 is a cross section through the mop showing it in one positionin full lines, and in an inverted position in dotted lines.

Figure 4 is a detail showing a section through the hinge member withpart of one of the plates shown therein.

Figure 5 is a detail showing one end of the hinge member at which a stopis provided for limiting the movement of the plates when being insertedin the hinge member.

In the drawing the mop is shown as it may be made, wherein numeral 1indicates the block of material forming the mop, numeral 2, the handleholding plate, and numeral 3, the wringing plate.

The mop I is preferably formed of a block of sponge rubber, however, itwill be understood that any suitable material may be used, and this isprovided with plates 4 and 5 indented in the opposite sides and securedtogether by rivets or bolts 6. Open fingers l, 8, 9 and I extend outwardfrom the plates 4 and 5, and the plates 2 and 3 are hingedly heldtherein. It will be noted, in Figure 4, that one of the plates 2 isshown in a vertical position, and, in this position, the plate is freeto slide with a bead II thereon inside of the opening between themembers 9 and I0, and these plates are moved inward until their leadingedges engage a stop I2 at the far side, thereby preventing the platessliding straight through when the device is being. assembled.

The plate 2 on the lower side of the mop, in the position shown inFigure 3, is permanently attached to a socketl3 in which a handle may beinserted, as shown in Figure 1, and the plate 3 is on the opposite sideof the mop, and these two plates are held together by buttons l4'and 15on a strand I 6. The strand passes through an opening I! in the plate 2,and is held in a notch I8 in the plate 3, and it will be noted that,when the position of the mop is reversed, the block I will be rotatedabout the hinge on the plate until it assumes the position shown indotted lines in Figure 3, and the plate 3 will be moved around until itis in the position indicated by the dotted lines, and, when it is inthis position, the button IE will be drawn downward with the strand I6in the dotted position, and with the button H! on the opposite side ofthe plate 2, in which it is indicated by the dotted lines, and, when theparts are in this position, the button l5 may be placed in the slot ISin which the button I4 is shown in full lines.

The hinge members are formed as shown in Figures 4 and 5,, with openhinge members spaced apart with spaces I9 between them, and the plates 2and 3 are provided with openings 20' through which the members I, 8, 9and I0 may extend when the plates are bent downward in the holding orgripping position. It will be understood, however, that these hingedparts may be formed in any manner or by any means, and also that theplates 2 and 3 maybe attached to the block of material in any othermanner or by any means.

It will be understood that other changes may be made without departingfrom the spirit of the invention. One of which changes'may be in the useof other means for attaching a handle to the plate 2, another may be inthe use of other means for holding the plates 2 and 3 together, andstill another may be in the use of other means for securing the platesto the block of material.

The construction will be readily understood from the foregoingdescription. In use the mop may be provided as shown and described, andit will be noted that the block I is removably attached to the handle sothat it may readily be removed and replaced as may be desired. The unitcomprising the block consists .of a mop element, indicated by thenumeral 5 with the plates 4 and 5, and the members i, 8, 9 and I0, allof which are permanently attached to the element I, and these are placedon the handle by inserting the plate 2 between the members 9 and Ill, asshown in Figure 4, and with the bead H on the inside, and then, afterthis is in place, turning the block to a horizontal position either asshown in full lines in Figure 3, or asindicated by the dotted lines.When this is in place, the plate ,3 may be inserted between. theelements I and 8 in a similar manner, and then this may be moveddownward to a horizontal position and the button I4 snapped in the slotI8. The projections I2 are provided at the far ends of the hinge membersin order to prevent the plates passing out of the opposite ends thereof.This installs themop in the working position, and, when it is desired touse the opposite edge, it is only necessary to move the button I4 out ofthe slot, turn the block I with the attachments completely around, asindicated by the dash lines, with the inner end of the plate 2 as acenter, and with the plate 3 assuming a horizontal position on the lowerside of the element I. When the complete unit has been turned to theposition indicated by the dotted lines, the button I5 is moved downward,with the strand I6 passing through the hole I1, and the button I5 maythen be snapped into the slot I8. This makes it possiblev to hold theelement I in working position eithen'above or below the plate 2 to whichthe handle is permanently attached. At the same time, when it is desiredto wring the mop or element I, it is only necessary to hold the handlein one hand, and press downward or upward on the plate 3, as, with themop in the position shown in full lines in Figure 3, one side of the mopmay be wrung, whereas, with the mop turned over to the positionindicated by the dotted lines, the opposite side may be wrung by forcingthe plate 3 upward. This makes it possible to wring both sides of themop by the simple movement of pressing downward or pulling upward on theplate 3, and, while this is taking place, the mop is firmly held by thehandle through the plate 2. It will also be noted that, with thisparticular hinge, it is possible to assemble the parts without screws,nuts or bolts, as the plates are assembled with a free sliding movementin the sides of the block of material which enables the consumer toconnect or assemble the metal parts with the rubber slab without usingscrews or tools of any kind.

Having thus fully described the invention, what we claim as new, anddesire to secure by Letters Patent, is:
